Answer 1

Dear Student,
Let's start with 4 smallest digits which are (0–3) which are total of 4.
Now arrange the smallest digit first 1 as 0 can't be first digit so Then repeat 0 for four times which makes 100000
Now place all small number in increasing manner 10000023. So final numbers is 10000023.
